Abstract
The aim of this paper is to design interactive teaching strategies with Interactive White
Boards (IWB) and examine their effectiveness in teaching biology. Following the trend of
integrating the IWB in teaching, in this study we tried to stress the advantages of IWB to provide
better and effective teaching of biology in schools.
The research was conducted with students from third year in two secondary schools in
Stip. Students were divided into two groups. IWB-group (n = 35) – which used white board in
biology classes and T-group (n = 35). T-group was the control group which applied classical
teaching where the teacher used Microsoft PowerPoint slides on the screen.
The results showed that compared with classical training, IWB is more effective in
presenting topics of biology, or, more specifically, the theme “cell division” which was
processed with both groups of students. Some limitations and areas for improvement were also
noted. These results can be used to inform educators on possible applications of the IWB‟s use
not only in biology but in other school subjects as well.
Key words: ICT, Interactive White Boards, biology, cell division, student perceptions.

Introduction
Subjects that are being taught in biology classes in high school such as cell division,
photosynthesis, cellular respiration, food chain and evolution are topics that are difficult to study
and learn. Teachers and students believe that the topic Cell division is the most difficult topic for
learning of all the topics. Many similar studies have shown that students of different ages and in
different classes have insufficient knowledge about cell division (Lewis et all,2000; Lewis and
Wood-Roinson, 2000; Smith, 1991). Lewis (2000) suggested that students have difficulty in
understanding the process of cell division because this topic requires good prior knowledge of
the basic structures of cell organelles that participate in the process of cell division. If they were
shown using a pictorial and understandable way, it would be much easier for students to
understand it. So teaching should emphasize the dynamic nature of cell division using a variety
of teaching aids such as pictures, movies and video clips to demonstrate changes of
chromosomes in different stages of cell division and make models of chromosomes which will
help them overcome the difficulties in learning.
The research was conducted with students from the third year in two high schools in Stip.
Students were divided into two groups. IWB-group (n = 35) - which in biology classes used a
white board and T-group (n = 35). T-group was a control group where classical teaching was
applied with the teacher teaching using Microsoft PowerPoint slides on the screen. In the group
that during the teaching of biology used the whiteboard - IWB group integrated teaching was
applied.
The results showed that compared with the classical ICT - integrated teaching, IWB is
more effective in improving the teaching of topics in the area of biology, or more specifically,
the topic Cell division which was processed with both groups of students.
The main advantages of IWB mentioned in literature and their potential in teaching
biology are explained as follows (Gloveretal., 2005; Holmes, 2009; Northcoteetal., 2010;
Smithetal., 2005; Walletal. , 2005):
2
Advantage 1. Flexibility and variability
IWB can be used in teaching students of different ages and for different topics. Its
features include notes, reviewing of material, saving drawings and text, movement of the planned
object and focusing. It can improve flexibility and mobility in the classroom. Therefore, IWB is
suitable for classes in teaching biology in secondary schools. Moreover, IWB can focus on
specific content and can expand multimedia objects based on teacher and student needs. Notes
about the content can also be made via IWB screen. In addition, teachers can record the teaching
process (including the notes) and interactions with students for later review.
Advantage 2. Multimedia / Multimodal Presentation
IWB represents a new integrated connecting of all teaching materials. A multimedia
presentation can attract the attention of students and help them understand abstract concepts. In
teaching biology, the visual nature of IWB presentations can enhance student learning by
delivering micro or dynamic representations of abstract concepts such as the process of cell
division or structures or functions within the body such as blood circulation. IWB also supports
multimedia and multimodal presentation. Most presentations can be simultaneously displayed on
the screen to meet the needs of students with different learning styles.
Advantage 3. Improving teaching efficacy
Teachers can display many multimedia resources on the IWB to improve their teaching
efficacy. For example, the structure of chromosomes can be displayed with images; video or 3D
models to help students make a model of the chromosome. In addition, students can use the IWB
to enhance and facilitate their learning process. Teachers can design learning activities for IWB,
which can help students to actively think and work on IWB. For example, teachers may provide
incomplete moving charts for the process of cell division for students to finish through
discussion. Teachers can also provide students with images of changes in chromosomes in each
phase of cell division and align images in correct layout and explain how the number of
chromosomes and DNA is modified.
3
Advantage 4. Planning and development of resources
IWB has a great teaching resource material relying on the database where teachers can
access a variety of animations and music on various topics, such as the anatomy of a frog, and
use it in the development of digital materials for teaching activities.
Advantage 5. Improving students’ skills to use ICT
Teachers can use the IWB to help students engage in learning better. Students can
improve their skills in using ICT through the use of the white board in teaching biology.
Advantage 6. Interactivity and participation during class
Interactivity is provided with IWB and can improve the interaction in the classroom and
make students and teachers feel closer to each other. They may have visual contact using a
laptop and the teachers are able to control the class. Moreover, IWB is more beneficial in
teaching courses that include survey (research) activities and request an increased participation
of students.
Advantage 7. Improving students’ motivation for learning
The ability of IWB to dynamically integrate audio and visual presentations can make the
teaching activities more vivid and realistic. Compared to standard 2D presentations and
textbooks, IWB can better attract the attention of students and improve their motivation to learn.
Advantage 8. Enhancing the understandings of students
IWB is characterized by visual nature and supports multiple displays, which not only
attracts the attention of students, but also enhances their understanding of the topics that are
covered. For example, IWB can simultaneously show 2D screen images of the structure of
4
chromosomes and 3D video demonstrations of the relationship between chromosomes, genes and
genetic information. This can not only improve the understanding of students with different
learning styles, but can also improve their ability to interpret the relationship between the 2D
images and 3D videos with information they transfer.
The above mentioned advantages of integrating the IWB in teaching biology in secondary
schools show that the introduction of IWB in class will provide teachers with a way to present
the dynamic nature of cell division, and the relationship between cells, chromosomes, genes and
genetic information with multimodal and multimedia presentations. Moreover, with the high
interactivity of the IWB students participate in learning and promoting learning motivation. In
this research we created digital teaching materials and activities that IWB uses for the learning of
cell division, in order to examine the effect of integration of IWB in the study of cell division.
Methodology
The research covered two secondary schools in the municipality of Stip with a total
number of respondents - 70 students. They were divided into two groups. The first group
included 35 students who were taught biology with a Smart board through integrated and
interactive teaching, and the second was the control group - 35 students (n = 35) who were taught
biology by applying traditional teaching where the teacher taught with Microsoft PowerPoint
slides on the screen.
InteractiveIWB -𝐒𝐦𝐚𝐫𝐭𝐁𝐨𝐚𝐫𝐝 𝑻𝑴
The IWB used in this study is the SmartBoardTM that uses analog resistive technology. It
is connected to a notebookor a computer through a USB cable, and the notebook or computer is
connected tothe projector. Signals of the projector are projected onto the IWB soby adjusting the
IWB,teachers can operate the computer by touching the IWB, as shown in Figure 1. This
interactive WB canimmediately save the written texts, drawings and other messages on the IWB
panel to theconnected computer.

Digital teaching materials and teaching method
This study is focused on the topic "Cell division" in teaching biology in a high school in
the Republic of Macedonia. The teaching contents for this topic cover three subtopics:
"Chromosomes and their significance", "Role of mitosis", and "Meiosis and sexual life
cycle."The teaching materials for„chromosomes and their significance‟ are focused on the
following concepts: chromosomes are located in the nucleus; chromosomes contain hereditary
material - genes to identify inherited personality characteristics; the number of chromosomes
varies in different species but it is always strictly constant for a certain species, homologous
chromosomes."Role of mitosis," "Meiosis and sexual life cycle" aim at enabling students to
understand when mitosis and meiosis happen in a cell, and why they are important for all life in
general.
Digital teaching materials that were used by teachers of biology classes in the study of
these teaching topics were mainly pictures, photographs and Adobe Flash animations. The
materials used in both groups incorporate the same concepts and teaching is carried out by the
same teacher. The main difference is that in the IWB group digital instructional materials can be
used on NoteBookTM software which is made possible by SMARTTM Technologies.Furthermore,
teachers can communicate with students through the IWB screen. In the control group, digital
instructional materials are presented in a classic way of teaching, presenting PowerPoint slides
through the projector screen, and the interaction between the teacher and students is limited to
verbal communication. The teaching methods in the experimental and control group are
explained below.

Teaching methods for the experimental group
Students have prior knowledge of the cell from previous lectures. They know that the
nucleus is related to heredity but they do not understand the contents of the structures responsible
for transferring hereditary information from generation to generation. Lewis (2000, b) in their
research found that students did not understand the relationship between the cell, chromosomes
and genetic information. If students need to develop a coherent conceptual objective to better
understand the genetics and inheritance, they first must well understand the relationship between
the basic structures - cell nucleus, chromosomes and genes.Hence, in the topic "Chromosomes
and their Significance" the teacher enables students to understand the relationship between the
cell nucleus, chromosomes, genes and genetic information via two-dimensional and threedimensional microscopic imaging. Likewise, aiming at students‟ better understand of the
relationship between the cell nucleus, chromosomes and genes, the teacher performs activities
with which he/she invites students to answer the questions and move on to the IWB collaborative
matches of the genetic structures.This section also includes an explanation of the structure and
function of the DNA. The teacher also implements activities for students to work together to
identify the relationship of blood between the child and its parents through their previous
knowledge of DNA copies, and to explain the reasons for their identicalness (Figure 2).

Students can also resolve misunderstandings about sex chromosomes (X, Y
chromosomes),they directly compare men‟s and women‟s karyotypes, differences between
themselves, and the number of chromosomes. In addition, students have access to Adobe Flash
animations to find out the number of chromosomes. After comparison, they may conclude that
different types have different numbers of chromosomes and that the number of chromosomes
does not imply a hierarchy of types (Figure 3).Finally, the concepts of homologous
chromosomes, polyploidy and gene alleles are displayed through human karyotypes. By
dragging and making separate homologous chromosomes together through IWB, students will
gain a better understanding of the concept. In order to enable students to clearly identify
differences in alleles, this information is represented by using images. Moreover, the concept of
ploids is represented by students who compare karyotypes of human somatic and reproductive
cells.
Figure 3. The teaching materials – examples from a teaching lesson, Stavreva Veselinovska, S., 2012)
During the processing of the teaching content "Mitosis" teaching activities are used to
help students understand the importance and the process of mitosis. The IWB screen is divided
into two parts. The left part presents the significance of mitosis, the process by which a cell is
divided into two identical cells. On the right side, IWB shows the process of mitosis but it does
not show how chromosomes change in the nucleus. Instead, students are enabled to actively
think about the changes on chromosomes in mitosis, and the teacher applies instructional
8
activities with which students will be forced to answer questions about the changes of
chromosomes in each stage.
Figure4. Screenshot of teaching materials (Stavreva Veselinovska S., 2012)
Furthermore, to clarify the students‟ misunderstanding of terminology they will learn
terms, including "chromosomal duplication", "separation of sister chromatids" and "one cell
divides into two identical cells" (see step 4 in Figure 4).
Figure. 5. The four steps of teaching the concept of mitosis in IWB group. The big rectangles in
this figure are the masks for the correct answers – example from a teaching lesson, Stavreva Veselinovska
S., 2012 .
After that, in order for the students to get a deeper understanding of changes in ploidies,
DNA quantity and the number of chromosomes, a picture of each stage of mitosis is projected on
the IWB display for students to work together in determining the process of mitosis in
9
subsequent stages (prophase, metaphase, anaphase, telophase) (Figure 5), and then they draft
diagrams of changes in chromosomes, DNA molecule and the number of chromosomes (see
section C in Figure 5).
Figure 5. Screenshot of the teaching materials for the concept of mitosis in IWB group
In "Meiosis and sexual life cycle" teacher also introduces teaching activities to enable
students to understand the importance of meiosis and when and where it happens. Human
karyotypes are used to help students understand that if meiosis does not occur in gametes before
fertilization, there can be a problem on tetraploidies. Then students learn about meiosis using
methods similar to those listed above.Students should identify the following concepts of meiosis:
"chromosomes replicate once, but divide twice", "there are four daughter cells" and "sister
chromatids divide during anaphase II". They made notes on the IWB screen and notice the
concepts that meiosis is the main cause of genetic variation in the sexual life cycle. They also
seek to demonstrate changes in the number of chromosome sets, the number of chromosomes
and DNA quantity.Finally, to enable students to distinguish between mitosis and meiosis, the
teacher presents two parallel cell divisions, mitosis and meiosis, sexual and asexual reproduction
on the IWB screen. Their similarities and differences are presented by the students.
Application of teaching methods in the control group
Digital teaching materials used in the IWB group and T group include the same concepts
presented by the same teacher. The main difference is that in the IWB group digital teaching
materials can be used for teaching on the IWB, while in the T group these digital instructional
materials are presented in a classical way using the projector for Microsoft PowerPoint slides on
the screen and the interaction between the teacher and the students is limited to verbal
10
communication. In other words, the experimental and control group are presented the same
instructional materials in the same order. The only difference is that in the experimental group,
the students are allowed to work together on the smart board during class. In the control group,
students answer questions verbally during the teaching activities, and the teacher presents the
teaching materials using PPT slides one by one.
Therefore, in the subtopic “Chromosomes and their significance" all teaching materials
are designed to allow students in the control group to learn the basic structures through images.
However, in the experimental group, students compete to answer questions and make a
connection between the basic structures on the smart board.In the control group, after the teacher
asks the questions, students compete to answer and then the teacher uses simple animations
embedded in PPT slides to present the relationship between the basic structures. Once students
answer the questions, the teacher shows the correct answer with animations included in PPT
slides. In addition, the teacher directly demonstrates Adobe Flash animations indicating that the
location, content and number of chromosomes varies in different species.
In the subtopic "The role of mitosis" teaching activities are used to help students
understand the importance of mitosis. The screen of the PPT presentation is divided into two
parts. The left side of the screen shows the importance of cell division - one cell is divided into
two identical cells. The right side of the screen shows a diagram of the process of mitosis, but not
the changes of the chromosomes in the nucleus.After implementing educational activities with
students, the teacher shows animations included in the PPT slides to show how chromosomes
and terminology change at each stage in the process of mitosis (Figure 6).To give students a
deeper understanding of the changes in the number of chromosome sets, the number of
chromosomes, and the quantity of DNA, the teacher also presents PPT slides and animations that
are embedded in PPT slides to show the process of mitosis and changes DNA and chromosomes
after carrying out the educational activities with students.The teacher teaches the subtopic
"Meiosis and sexual life cycle" in the same way as the subtopic "Role of mitosis." The table also
shows the animations embedded in PPT slides after the teacher completes the teaching
interactive activities with his/her students.

Research
To understand how the integration of IWB in teaching affects the effectiveness of
teaching in secondary schools in the Republic of Macedonia, this research uses a quasiexperimental design to divide the participants into the experimental group (IWB group) and the
control group (T-group). The IWB group is taught in a teaching environment that is integrated
with the IWB, while the control T-group is taught using classical ICT, where the teaching is
performed using Microsoft PowerPoint slides with a traditional projector screen through a
projector. However, both groups are taught by the same teacher. Beforeteaching, studentshavea
pre-testing of the overall assessment in order to understand the students‟ initial knowledge. Then
students receive five classes in which information technology is integrated into instruction. After
the five classes, students take a post-test for the overall assessment.
Collecting data and analysis
The collected data are quantitative data, including pre-test and post-test results of the
overall assessment. To examine how to integrate smart whiteboard in teaching in secondary
schools for the topic cell division and the effectiveness of student learning, this study uses two
different types of techniques for data analysis. First, to examine the effectiveness of two different
types of teaching methods, ANCOVA was conducted to calculate the overall assessment.The
results of the pre-test of the overall assessment is taken as an independent variable in two
different types of teaching methods as a fixed factor and the results of the post-test of the overall
assessment as the dependent variable. This analysis aims to understand how two different types
of teaching methods influence the effect of high school students‟ learning.
Results
To examine the effectiveness of IWB integrated teaching and classical ICT integrated
teaching in teaching biology in secondary schools, the statistical processing of the results was
made with ANCOVA to analyze the data.
Effectiveness of the two different types of teaching methods
To understand the impact on the learning effect of two different types of teaching
methods in secondary schools (TTM - types of teaching method), this study compares the effects
of students' learning from IWB group and T-group using ANCOVA. TTM is taken as the
14
independent variable, the results of the pre-test of the overall evaluation are taken as the
covariate, and the results of the post-test of the overall evaluation are taken as the dependent
variable. BeforeANCOVA, the homogeneity of variance assumption was tested. The Levene‟s
test forequality of variances was not significant (F =1.279, p > 0.05). In addition, the assumption
ofhomogeneity of regression coefficients was also tested (F =1.279, p > 0.05). The
resultsindicate that neither homogeneity assumption was violated. The results of the
ANCOVAanalysis are shown in Table 2.
Table 2 shows that the pre-test scores have a significant influence on the post-test scores
(F=10.694, p<0.01). Further, the TTM also has a significant influence on the scores of posttest
(F=19.67, p<0.01). The result means that student learning in instructional environmentsusing the
two different types of teaching method has significantly different learningeffectiveness. It is
found that studentsin the IWB group have significantly better learning effectiveness than those in
the T group.

Conclusion
The topic "Cell division - Mitosis and Meiosis" has always been one of the most difficult
topics for learning and teaching for both students and teachers. This fact is confirmed by studies
made by Brown, 1995 and Oztap et al., 2003. They argue that the application of certain teaching
methods is one of the reasons for the difficulties of students in learning the topic of cell
division.To assist students in learning Brown proposes the dynamic nature of cell division that
should be emphasized and that the teachers need to properly utilize 2D and 3D images enable
15
students to make a model of a chromosome. The results of this study show that, compared with
classical ICT - integrated teaching, IWB is more effective in the teaching and learning of cell
division.
Of all the sub-topics of cell division, IWB is especially effective in helping students to
learn the "Role of mitosis" and "Meiosis and sexual life cycle." Classical ICT integrated teaching
can only improve effective learning of the subtopic "Chromosome and its importance." This may
be the case because, in comparison with classical ICT integrated teaching, IWB can better
consolidate multimodal representations, including key concepts such as genes, chromosomes and
genetic information.Students can consequently develop more coherent conceptual framework to
serve as the basis of their learning of cell division. This can eliminate the difficulties in learning
caused by basic concepts - cell nucleus, gene and genetic information, and the relationships
between them that are implied separately in different teaching topics (Lewis, 2000b).
The interactive nature of IWB improves the interaction between teacher and students and
peers. The teaching of the two subtopics "Role of mitosis" and "Meiosis and sexual life cycle"
this study attempts to make interactive nature of closely integrated IWB in teaching
activities.Students work together to complete tasks for answering questions about the processes
of the two types of cell division and considering the difference between mitosis and meiosis
compared with chromosome duplication, the number of divisions, the number of daughter cells
and
genetic
composition.
This
may
explain
why
students
have
better
learning
effectiveness.According to several researchers (Levy, 2002; Torf and Tirotta 2010; Wall,
Higgins and Smith, 2005), students think that when they are allowed to use the IWB, their
learning can be significantly improved and that their learning process can be better facilitated.In
classical ICT integrated teaching, the interaction between teacher and students is limited to
verbal communication and messages are communicated through the PPT slides in a more linear
way. In comparison, IWB can better integrate multimedia presentations. This may be the reason
why students have lower effective learning when traditional ICT-integrated teaching is applied.
Based on the research findings, this study argues that teaching methods are the reason
why cell division is considered a difficult topic to study in high school, according to Brown
(1995) and Lewis (2000b). Oztap (2003) showed that students lacked a coherent conceptual
working framework and often felt confused about genetic terminology. If the relationship
between the basic structures such as cell nucleus, chromosomes and genes can be clearly
16
presented and students can assist in making models of chromosomes, they will be able to
overcome difficulties in learning.If the relationship between the basic structures such as cell
nucleus, chromosomes and genes can be clearly presented and students can assist in making
models of chromosomes, they will be able to overcome difficulties in learning. Brown (1995)
also stated that during the teaching activities, both 2D and 3D images can provide students
assistance in making models of chromosomes.According to Brown, this study suggests that
during teaching activities, teachers can try to integrate multimedia into learning about
"Chromosome and its importance." For example, images of colored cells under a microscope can
be used for demonstrating the relationship between the cell nucleus and chromosomes, 2D and
3D images can be used to show the structure of the chromosome, and dynamic videos or
animations can be used to present chromatin in a eukaryotic chromosome.After students get a
clearer picture (understanding) of the basic genetic concepts and the development of a more
coherent developmental framework, they will find an easier way to learn more about cell
division.
Currently, classical ICT integrated teaching always uses Microsoft PowerPoint slides
(PPT slides) to enrich teaching and to break the monotony of the lesson. While PPT slides allow
teachers to integrate multimedia presentations, they do not support Adobe-Flash animations basic interactive media. They can be presented only in a linear manner or page after page when
used
in educational activities,
which makes them educational opportunities
more
limited.However, this study integrates IWB in teaching. IWB can integrate both multimedia and
Adobe-Flash animations - basic interactive media presentation to help teachers perform
multimedia or multimodal teaching. The differences between the two types of cell division can
be clearly displayed, allowing better understanding. A key feature of IWB - high interactivity
allows teachers to have more contact and interaction with students, in addition to verbal
communication.It is also easier for teachers to make facilitating interactive teaching and
cooperation between students. Teachers and students feel closer to each other, as claimed by
Wood (2002), and students are more motivated to concentrate and participate in educational
activities (Homles 2009, Northcote, 2010). These advantages greatly outweigh the limitations of
PPT slides in teaching and students learn effectively.Based on the findings of this study, the
construction of a chromosome model is vital in teaching cell division. The dynamic process of
cell division and the micro-view of chromosome changes are also crucial to overcome the
17
difficulties in understanding cell division. If ICT, multimedia and multimodal presentations are
properly used, student learning will be more effective when they learn about cell division.
